The movie will be titled ‘Gotham City Sirens’ and will take direct influence from the comic book series of the same name that saw Harley Quinn team with the likes of Catwoman and Poison Ivy. It shall be written by the screenwriter of the upcoming ‘Tomb Raider’ reboot and ‘Sherlock Holmes 3’, Geneva Robertson-Dworet, but there is yet to be word on confirmed secondary characters or the actors that will portray them.

No release date has been announced, but it is expected that production will be fast-tracked by Warner and the release possibly moved ahead of their plans for ‘Suicide Squad 2’ and a stand-alone Deadshot movie.
